Commissioning is often the only time when the motor, driven equipment, controls and process team are available together. Use that window to create a comparison set, not just a pass/fail sheet.

Data group Context to retain Future use
Voltage/current/power Load, phase and drive state Loading and supply comparison
Temperature Ambient, elapsed time and sensor Thermal trend
Vibration Point, direction, speed and load Mechanical condition trend
Process Flow, pressure, rate or valve state Explain motor demand

Make the baseline repeatable

Use named measurement points and calibrated instruments. Capture several approved operating points where the duty varies. Record alignment, lubrication, protection settings and VFD parameter backup with the data set.

Store raw files, summary, date, machine serial number and configuration revision together. When equipment is repaired or materially changed, create a new baseline rather than overwriting the original.
